Patch 4.3's mounts and how to get them

The World of Warcraft Armory has been updated with new data on the various mounts added to the game with patch 4.3. This data includes confirmation of drop locations. At least two new mounts are being added to in-game holidays, as well as the reveal of the Glory of the Dragon Soul Raider meta achievement. Other mounts, like Experiment 12-B, are now confirmed rare drops off of the Ultraxion encounter in Dragon Soul.
